The concept of targeting multiple disease etiologies that lead to cognitive impairment in the neurodegenerative disorder Alzheimer’s disease (AD) is challenging the widely held assumption that “ silver bullet” agents are superior to “ dirty drugs” in drug therapy. Accumulating evidence in the literature suggests that a drug with two or more mechanisms of action targeted at multiple etiologies of the same disease may offer more therapeutic benefit in certain disorders than a drug that targets one disease etiology only. In addition, such multiple mechanism/multifunctional drugs may exhibit a more favorable side effect profile than a polypharmaceutical combination of several drugs that individually target the same disease etiologies than those identified for a single multifunctional drug. In this chapter, we offer a synopsis of therapeutic strategies and novel investigative drugs, developed in our own and other laboratories, which modulate multiple disease targets associated with AD and cognitive impairment disorders.
